It appears as though Toronto PATH did have an iPhone app of its own at one point but, as of 2018, that app has been removed from the app store.

"It's an amazing piece of infrastructure, but current maps don't do it justice," says Toronto-based inventor and entrepreneur Eric Rotberg of the underground network.

"I've noticed that a lot of people, myself included, kind of dread this place," he continued, pointing to how notoriously difficult the PATH is to navigate. "So I decided to do something about it."

Pathmap can give you custom directions for Toronto's underground maze of stores and restaurants wherever you happen to be. Screenshot of pathmap.ca.

Working with a team of developers, Rotberg has created a mobile website called pathmap that uses "a unique navigation algorithm to help users orient and navigate in the PATH."

Robterg says that iOS and Android versions of pathmap are in beta now, but will soon be released with additional features, such as a step-by-step directions ("Go right at the Tim Hortons. Continue past the Swarovski store.")

In the meantime, anyone can pull up the web-based version of pathmap on a smartphone and figure out how to get from point A to point B inside the PATH almost immediately.

If you're at City Hall, for example, and want to get to Burger King, you can select those two places from a drop down menu of roughly 11,000 businesses and voila: a map you can actually follow.

"Users can find their current location and plot a walking path to their desired destination," says Rotberg, by "simply selecting a location on the map."

Still, as so many people wonder all the time, why can't we just use Google Maps or some sort of app to find our way using GPS? Like we do above ground?

Because, as Rotberg explains, GPS doesn't work in the PATH.

This is why we can only see where specific stores are located in relation to the streets above them on Google Maps — which doesn't help much since the PATH has a completely different and unique layout.

Rotberg says that with pathmap, you can find your location easily by typing in the name of any business you are near in the search bar.

The app will know where you are based on the location of that business and guide you to where you'd like to be.

Toronto's "PATH" network is downtown Toronto’s (mostly) underground walkway linking 30 kilometres of shopping, services and entertainment. It's the world's largest underground pedestrian network, yet, there is still no proper smartphone app available to guide. @TorontoCommspic.twitter.com/zWNkGDypLm

It's no GPS, but this system is the farthest we've gotten in terms of digital navigation tools for the PATH, so far, and it's still incredibly helpful for figuring out how to find your way to a specific location within the most confusing underground mall of all time.

"The application is fast, stable and user feedback has been overwhelmingly positive," says Rotberg of the app.

"Our vision is to collaborate with the City of Toronto to reach a larger user base, incorporate many of the desired features, and keep the app ad free."
